Ans: 4 – 5

= – 1

**(4) 2 less than – 7**

Ans: – 7 – 2

= – 9

**(5) 7 + **

-3

=?

Ans: 7 + 3

= 10

**(6) (- 42) + (- 35) =?**

Ans: – 42 – 35

= – 77

**(7) (- 37) + 6 =?**

Ans: – 37 +6

= – 31

**(8) 49 + (- 27) =?**

Ans: 49 – 27

= 22

**(9) The successor of – 18 is**

Ans: -18 + 1

= – 17

**(10) The predecessor of – 16 is **

Ans: – 16 – 1

= – 17

**(11) The additive inverse of – 5 is **

Ans: 5

**(12) – 12 – (- 5) =?**

Ans: – 12 + 5

= – 7

**(13) 5 – (- 8) =?**

Ans: 5 +8

= 13

**(14) The sum of two integers is – 25. If one of them is 30 then the other is **

Ans: – 25 – 30

= – 55

**(15) The sum of integers is 20. If one of them is – 5 then the other is **

Ans: 20 – (- 5)

= 25

**(16) The sum of two integers is – 13. If one of them is 8 then the other is**

Ans: – 13 – 8

= – 21

**(17) On subtracting – 8 from 0, we get**

Ans: 8

**(18) 8 + (- 8) =?**

Ans: 8 – 8

= 0.

**(19) (- 6) + 4 – (- 3) =?**

Ans: – 6 + 4 + 3

= – 6 + 7

= 1

**(20) 6 – (- 4) =?**

Ans: 6 + 4

= 10

**(21) (- 7) + (- 9) + 12 + (- 16) =?**

Ans: – 7 – 9 + 12- 16

= 12 – (7 + 9 + 16)

= 12 – 32

= – 20

**(22) On subtracting 8 from – 4, we get**

Ans: – 4 – 8

= – 12

**(23) On subtracting – 9 from – 6, we get**

Ans: – 6 – (- 9)

= – 6 + 9

= 3

**(24) On subtracting – 5 from 10, we get **

Ans: 10 – (- 5)

= 10 + 5

= 15

**(25) (- 6) x 9 =?**

Ans: – 54

**(26) (- 9) x 6 + (- 9) x 4 =?**

Ans: – 54 + (- 36)

= – 54 – 36

= – 90

**(27) 36 ****÷**** (- 9) =?**

Ans: – 4
